Relaxation of Extracellular Matrix Forces Directs Crypt Formation and Architecture in Intestinal Organoids

Jan. 31, 2020

Intestinal organoid protocols rely on the use of extracellular scaffolds, typically Matrigel, and upon switching from growth to differentiation promoting media, a symmetry breaking event takes place. During this stage, the first bud like structures analogous to crypts protrude from the central body and differentiation ensues. While organoids provide unparalleled...

Development of MPRA for use in primary human CD4 T cells

Resolving mechanisms of immune-mediated disease in primary CD4 T cells

Jan. 31, 2020

Deriving mechanisms of immune-mediated disease from GWAS data remains a formidable challenge, with attempts to identify causal variants being frequently hampered by linkage disequilibrium. To determine whether causal variants could be identified via their functional effects, we adapted a massively-parallel reporter assay for use in primary CD4 T-cells, key effectors...

Reaction Environment Effect on the Kinetics of Radical Thiol–Ene Polymerizations in the Presence of Amines and Thiolate Anions

Jan. 31, 2020

Because of facile implementation, quantitative conversions, and an insensitivity to oxygen, water, and most organic functional groups, radical-mediated thiol–ene coupling (TEC) reactions have emerged as a valuable tool in macromolecule synthesis. It was recently demonstrated that the kinetics and conversions of thiyl radical-mediated reactions are adversely affected in the presence...

UBAP2L Forms Distinct Cores that Act in Nucleating Stress Granules Upstream of G3BP1

Jan. 31, 2020

Stress granules (SGs) are membraneless organelles that form in eukaryotic cells after stress exposure [ 1 ] (reviewed in [ 2 , 3 , 4 ]). Following translation inhibition, polysome disassembly releases 48S preinitiation complexes (PICs). mRNA, PICs, and other proteins coalesce in SG cores [ 1 , 5 ,...

Remodeling of Zn2+ Homeostasis Upon Differentiation of Mammary Epithelial Cells

Jan. 16, 2020

Zinc is the second most abundant transition metal in humans and an essential nutrient required for growth and development of newborns. During lactation, mammary epithelial cells differentiate into a secretory phenotype, uptake zinc from blood circulation, and export it into mother’s milk. At the cellular level, many zinc-dependent cellular processes,...

Two-stage ML Classifier for Identifying Host Protein Targets of the Dengue Protease

Jan. 13, 2020

Flaviviruses such as dengue encode a protease that is essential for viral replication. The protease functions by cleaving well-conserved positions in the viral polyprotein. In addition to the viral polyprotein, the dengue protease cleaves at least one host protein involved in immune response. This raises the question, what other host...

Spaceflight-Induced Bone Tissue Changes that Affect Bone Quality and Increase Fracture Risk

Jan. 6, 2020

PURPOSE OF REVIEW: Bone mineral density and systemic factors are used to assess skeletal health in astronauts. Yet, even in a general population, these measures fail to accurately predict when any individual will fracture. This review considers how long-duration human spaceflight requires evaluation of additional bone structural and material quality...

RNase L promotes the formation of unique ribonucleoprotein granules distinct from stress granules.

Jan. 6, 2020

Stress granules (SGs) are ribonucleoprotein (RNP) assemblies that form in eukaryotic cells as a result of limited translation in response to stress. SGs form during viral infection and are thought to promote the antiviral response since many viruses encode inhibitors of SG assembly. However, the antiviral endoribonuclease RNase L also...

 Generation of varied porous scaffolds using clickable microgel building blocks

Porous bio-click microgel scaffolds control hMSC interactions and promote their secretory properties

Dec. 31, 2019

Human mesenchymal stem/stromal cells (hMSCs) are known to secrete numerous cytokines that signal to endogenous cells and aid in tissue regeneration. However, the role that biomaterial scaffolds can play in controlling hMSC secretory properties has been less explored. Here, microgels were co-assembled with hMSCs using three different microgel populations, with...

A gene expression atlas of embryonic neurogenesis in Drosophila reveals complex spatiotemporal regulation of lncRNAs.

Dec. 31, 2019

Cell type specification during early nervous system development in Drosophila melanogaster requires precise regulation of gene expression in time and space. Resolving the programs driving neurogenesis has been a major challenge owing to the complexity and rapidity with which distinct cell populations arise. To resolve the cell type-specific gene expression...
